Structural, morphological, magnetic, and dielectric properties of copper-substituted Cu\(_{X}\)Zn\(_{(1-X)}\)Fe\(_{2}\)O\(_{4}\) nanoparticles: Green synthesis

Structural, Magnetic, and Dielectric investigations on the “CuX Zn(1-X) Fe2O4” X with stoichiometry (X=0, 0.3, 0.5, 0.7, and 1) were synthesized by solution combustion method using Aloe Vera extraction. The X-ray diffraction method was utilized to characterize the as-synthesized Cu-Zn ferrites. The results indicated the presence of cubic spinel structure with Fd‒3 m space group, and absence of other contaminates. The lattice parameter was found to increase with the increase in Zinc concentration. The patterns of TEM confirm that the particle is within the nanometer range (35 nm to 50 nm). Magnetic properties investigated by vibrating sample magnetometry, reveal that the MS, MR, and HC values decrease with an increase in Zn concentration. The dielectric studies performed at room temperature show that the increase in frequency decreased the dielectric loss and Cu0.5Zn0.5Fe2O4 exhibits higher dielectric constant and dielectric loss are studied at the frequency range studied. Thus, the prepared samples have potential applications in semi-conductor and EMI shielding devices.
